We are observing memory leak in WebLogic OSB when Java agent is enabled. The heap degradation occurs in about 1/2 weeks after the reboot.
We consulted with Oracle support team. After a heap dump and its analysis, Oracle support team said that it was caused by APM Introscope classes.
In particular, the class that they see as culprit is the following one: "com.wily.util.extension.JarExtension$AllPermissionsClassLoader".
This progressive degradation of the heap memory was slow, but after some time, it is notable, and it is apparently happening in every WebLogic OSB instance that we have.
Release : 10.7.0
Component : APM Agents
Oracle Service Bus : 184.108.40.206
Java version : 1.8.0_202
We can proposed the following workaround.
You can disable the ProxyTracing in osb.pbd
-> TurnOn: ProxyTracing
Example to disable:
In file /<APM-Agent-HOME>/core/config/OSB.pbd
